Features
․Package in 8mm tape on 7〞diameter reel.
․Compatible with automatic placement equipment.
․Compatible with infrared and vapor phase reflow solder process.
․Mono-color type. ․Pb-free.
․The product itself will remain within ROHS complaint Version.
Descriptions
․The 17-21 SMD Taping is much smaller than lead frame type components, thus enable smaller board size, higher packing density, reduced storage space and finally smaller equipment to be obtained.
․Besides, lightweight makes them ideal for miniature applications. etc.
Applications
․Automotive: backlighting in dashboard and switch.
․Telecommunication: indicator and backlighting in telephone and fax.
․Flat backlight for LCD, switch and symbol.
․General use.
Precautions For Use
1. Over-current-proof
Customer must apply resistors for protection, otherwise slight voltage shift will cause big
current change ( Burn out will happen ).
2. Storage
2.1 Do not open moisture proof bag before the products are ready to use. 2.2 Before opening the package: The LEDs should be kept at 30℃ or less and 90%RH or less.
2.3 After opening the package : The LEDs should be kept at 30℃ or less and 70%RH or less(Floor life).
However, it's recommended that the LEDs should be used within 168 hours (7 days) after opening
the package. If unused LEDs remain, it should be stored in moisture proof packages.
2.4 If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the
storage time, baking treatment should be performed using the following conditions. Baking treatment : 60±5℃ for 24 hours.
3. Soldering Condition
3.1 Pb-free solder temperature profile
3.2 Reflow soldering should not be done more than two times.
3.3 When soldering, do not put stress on the LEDs during heating.
3.4 After soldering, do not warp the circuit board.
4.Soldering Iron
Each terminal is to go to the tip of soldering iron temperature less than 350℃ for 3 seconds within once in less than the soldering iron capacity 25W. Leave two seconds and more intervals, and do soldering of each terminal. Be careful because the damage of the product is often started at the time of the hand solder.
5.Repairing
Repair should not be done after the LEDs have been soldered. When repairing is unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.
